I don’t usually like to talk about highways. I despise traffic. Trucking – unless it involves 40’ TEU’s being lifted onto a post-Panamax boxship or perhaps a 53’ unit being driven smartly onto an LNG-powered ConRo ship – just isn’t my bag, either.

When talk about barge carrier people often think about LASH (Lighter Aboard SHip), SeaBees which equipped with the rail mounted gantry crane or a massive stern lift. Can a common barge carries a barge for transportation? And how to launch the…

The opah or moonfish is a large pelagic fish with a colorful and deep body. It can grow up to six feet in length with a vertical measurement of over four feet, but a breadth or width of less than eighteen inches. It weighs up to 600 pounds.

Less than two weeks ago, a vote by the Massachusetts Board of Higher Education (BHE) confirmed Francis X. McDonald as the 38th president of the Massachusetts Maritime Academy. That’s not especially earthshaking news, and outside our somewhat narrow “maritime” sphere, it garners even less attention.

The US Revenue Cutter Ingham was launched in 1832 as part of the Morris-Taney class. The cutters were designed for multiple missions including, but not limited to, law enforcement, fighting pirates (which were particularly prevalent in the Gulf of Mexico and around Cuba), and augmenting the US Navy.

First discovered on the deep seafloor of Monterey Bay in 2002, bone-eating worms (Osedax) seem to dine exclusively on the bones of whale carcasses that fall to the ocean floor (so-called whale falls). They are about one inch in length and composed entirely of soft tissue.
